Fooled by Randomness Theory

The theory, from Taleb's book of the same name, that humans systematically misinterpret random events, seeing patterns where none exist and attributing skill to luck. Fooled by Randomness Theory argues that we are narrative creatures, wired to find stories in noise, to see causes where there are only correlations, to believe we understand what is actually random. Successful traders are often just lucky, not skilled; failed entrepreneurs are often just unlucky, not incompetent. The theory explains why we overestimate our ability to predict, why we trust experts who are actually random, why we build theories on statistical flukes. It's the foundation of skepticism about success stories, about "genius" CEOs, about anyone whose track record could be explained by chance. The theory doesn't deny skill; it insists on distinguishing skill from luck—and shows how bad we are at that distinction.

Example: "The hedge fund manager had ten years of brilliant returns. Fooled by Randomness Theory asked: could this happen by chance? The math said yes—a few funds will always be lucky by pure randomness. The manager was celebrated as a genius until the next ten years revealed the truth: he'd been lucky, not skilled. His investors had been fooled by randomness."
